There are few conversions in HVAC as simple as MBH to BTU/h. Basically, we are converting a t*housands British Thermal Units per hour* (**MBH**) to *British Thermal Units per hour* (**BTU/h** or **BTU/hr**). To help you out with the conversion, we prepared an **MBH to BTU/h calculator** *(insert MBH, get BTU/h)* as well as a 0.01-50 MBH to BTU/h ** conversion chart**.

*Quick Example:* Say you want to convert **12 MBH to BTU/h**. You just insert 12 MBH in the calculator (or check the chart below), hit ‘Calculate’, and the calculator tells you immediately that 12 MBH is equal to **12,000 BTU/h**.

Here is this online calculator:

You can try inputting, say, **36 MBH** in the calculator and see that you will get the BTU/h equivalent as a result (36 MBH is equal to **36,000 BTU/hr**). You can do this conversion in reverse with this BTU/h to MBH calculator.

Let’s have a look at how simple this conversion is (we can do the math in our head):

### MBH To BTU/h Formula

MBH in HVAC stands for ‘thousand BTUs per hour’. That ** ‘M’** is just a Roman numeral M that means

*‘thousand’*or

*‘1000’*. When we calculate heating or cooling capacities, we just use this conversion rule (it’s in the name):

**1 MBH = 1000 BTU/h**

Namely, 1 MBH is equal to 1000 BTU/h. We can write this relationship in the following equation:

**BTU/h = MBH Ã— 1000**

To convert MBH to BTU/h, we just need to divide MBH by a factor of 1000 to get the BTUs/h.

Quick Example: *How many BTU/h is 9 MBH?* Let’s insert 9 MBH in the formula above and calculate the result:

BTU/h (9 MBH) = *9 MBH* Ã— 1000 = *9000 BTU/h*

We see that 9 MBH is equal to **9000 BTU/h**. Many portable and window air conditioners, for example, have 9 MBH or 9000 BTU/h cooling capacity.

You can do this calculation in your head but just for a bit of added help, we created this neat MBH to BTU/hr chart you can check and get the BTU/h right away:
